Came up with a somewhat great idea of taking piercing aqua blue and mix it with really dark grey/black eye shadow, and voila! I really think this suits a turquoise eye colour like mine, even though the advice usually says you should go with a shadow that’s not like your eye colour. I don’t think it’s true, I think if you have piercing blue eyes it can be really nice with a blue shadow on your eyelids. Just make sure you blend and mix it with another colour, like I did in this one. If you do so, you won’t get the feeling of it being over the top.
Btw, the pic on the top is taken in broad daylight, the other compilation of pics are taken in a damp room, which makes my eyes look more greyish.
